Stereo: 1/2/4/8/16 ohms.
Bridge Mono: 2/4/8 ohms.
Input Sensitivity (referenced to 8 ohm rated output): 1.4V, 32 dB gain, and 26 dB gain.
Voltage Gain (referenced to 8 ohm rated output):
Required AC Mains: Universal AC input, 100- 240VAC, 50/60 Hz (±10%). Maximum AC mains voltage 264VAC.
AC Line Connector: Five cordsets supplied with amplifier (USA, UK, European, Australia, India).
Front Panel Controls and Indicators
Bridge Mode Indicator: Amber LED illuminates when the amplifier is set to
Ready Indicator: Green LED, one per channel.
On (bright): Ready.
On (dim): Onset of compression.
Off: Thermal failure.
Signal Indicators: One green LED per channel.
Solid green: Input signal is above
Bright green: Channel’s output signal has reached the onset of audible clipping.
Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available. The LED will flash when the AC line voltage is 10% above or below the nominal rated value.
Data Indicator: Yellow LED on front panel indicates network data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online
Power Switch:
Volume Control: Precision detented attenuator with 31 steps,
Volume Control LED Ring: A ring of green LEDs around each volume control show the position of the control. Entire ring flashes when channel is muted. Can be converted to be a level meter.
Back Panel Controls, Indicators and Connectors
Power Cord Connector: Detachable 20 amp IEC inlet. Cord locks with suppliled cord retention clip. Voltage range is indicated above IEC inlet.
Reset Switch/Circuit Breaker: If the current draw of the amplifier exceeds safe limits, this breaker automatically disconnects the power supply from the AC mains. The switch resets the circuit breaker.
Output Connectors: Two
Analog Input Connectors: A
Analog Loop Thru Connectors: Two male XLR passive analog loop through.
Mode Switch/Indicator: Sets amplifier to Stereo, Bridge, or Input Y mode. OFF=Stereo, YEL=Bridge, GRN=Y.
Network Connectors: Two Neutrik® Ethercon connector accepts
Data Indicator: Yellow LED on back panel indicates network data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online.
Preset Indicator: Green/yellow LED flashes to signal the number of the current preset. LED is green if current preset is active, or is yellow if current preset is modified.
Input Sensitivity Switch:
